Island Mountain Tops
Boating hazards on Flathead Lake are rare, but you need to be aware of some potential trouble spots. Remember that the lake covers many mountain peaks and depending on the water level, some can be just under the surface. Hazards that can cause damage to boats are typically well marked.
There are only a few small islands with the largest being Wild Horse Island. The lake is full of native Bull Trout and Cutthroat trout, and huge Lake trout, along with perch and whitefish.
Common Boating Hazards
The most common hazards are flotsam in the form of logs carried to the lake from the rivers that feed Flathead Lake. The thing to be aware of is that many of these logs can be floating partially submerged or even under the surface. There are very few permanent boating hazards in Flathead Lake. The only submersed hazards are well marked such as this buoy at the mouth of Somers Bay.
